REVOLVING BUCKET-STRAINER.

SPECIFICATION forming part of Letters Patent No. 421,253, dated February 11, 1890.

Application led July 8, 1889'. Serial No. 316,796. (No model.)

To a/ZZ whom, t may concern.-

Be it known that I, JOHN TILDEN DOR-, a citizen of the United States, residing at Bayou Sara, in the parish of West Felicianaand State of Louisiana, have invented certain new and usefulImprovements in a Revolving Bucket-Strainer; andI do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in that class of devices known as canejuice strainers.7

It has for its object to provide an apparatus whereby the cane-juice and particles of bagasse received from a crushing-mill are separated and discharged through their respective channels; and the improvements consist lin the construction, novel combination, and

adaptation of parts, hereinafter described and claimed.

In the drawings, Figure l is a vertical sectional View of my improved straining and separating machine in an operative position. Fig. 2 is a vertical transverse sectional View of the same. Fig. 3 is a detail face View of one of the buckets, showing the devices for securing the same to the periphery of the revolving wheel. Fig. 4 is a detail back View of the same, and Fig. 5 is a longitudinal sectional View taken on the line oc oo of Fig. 3.

Referring to said drawings by letter, A indicates the frame or casing of the machine, which may be of any approved construction having the ordinary base-supporting timbers.

B indicates upright standards, arranged -within the casing` to afford a bearing for the shaft of the perforated straining-wheel, presently to be described.

C indicates the improved revolving straining wheel. This wheel C, which may be braced by spokes or other suitable means, is keyed cna shaft journaled in the bearings in the standards B, before described, and it derives its motion from a band-wheel a, also keyed on said shaft outside the casing. This straining-wheel C also has a gauze or perforated periphery D, and is provided with ra dial fianges E at each side of the said. periphery D. These flanges E are also perforated, and they serve to prevent the bagasse within the buckctsfroin escaping from the sides thereof while being pressed, and at the same time allow the extracted juice to pass through the perforations down upon and through the bottomv strainer, hereinafter described.

F indicates my improved yielding strainingbuckets, of which there may be any suitable number, according to the diameter of the straining-wheel employed. These buckets, which are of a width slightly less than that of the straining-wheeL'to allow a passage for the juice thereon, are secured equidistant upon the periphery of the strainingwheel, their lower horizontal edge being attached thereto in a manner presently to be described, so as to normally keep tliebuck- Vets in an angular extended position with respect to the periphery of said wheel.

The buckets are provided with a gauze straining-face portion G, through which the juice escapes when the bucket has been depressed. The side edges of the gauze strip G are secured, respectively, in parallel strips c, each of which is bent longitudinally upon itself to form a seat or sheath for the edges thereof, which are secured therein by the bolts d. The base edge of the gauze is protected by a transverse strip e, formed integral with and connecting the parallel strips c, before described. The upper edge of the said strip adjacent to the friction-roller is preferably left unprotected. The outer side of each of the transversely-bent strips c is longer than its fellow and extends longitudinally above and below the same, theupper extensions being turned to form bearings for the shaft of the friction-roller andthe lower ones to form bearings for a securing. device, presently to be described.

II indicates a frictioirroller provided at the top of the bucket. This roller H, the shaft of which is journaled in the upper bearings of the strips c, serves to engage the periphery of the pressingqvheel, hereinafter described, and guide the bucket under and pass the same.

f indicates a transverse rod `journaled in the lower-turned bearings of the extended portion of the strips c. This rod f is provided IOO at its ends with angular imvardly-directed sharpened portions adapted to enter the periphery of the straining-wheel C and secure the lower end of the bucket thereto.

h indicates rearwardly-extended springarms, which serve to keep the bucket in a normally-extended position. These springarms h are sheathed in the bent portions of the strips c and are secured therein by the bolts d, before described. The rearwardlyextended portions of t'he springs are secured to the peripheryT of the straining-wheels by the staples t', shown in position thereon.

'Il' indicates the pressing-roller for extracting the juice from the bagasse within the buckets. This roller I-l, which is journaled in'a suitable bracket depending from the top of the casing, is so arranged with respect to the straining-wheel that it will engage the face of the passing` buckets and depress the same, thus forcing` the extracted juice through the gauze periphery of the wheel and the flanges thereof down upon a horizontal bottom strainer, while the pressed bagasse is carried by the buckets to a point above the bagassc discharge-trough, which is discharged upon said trough and carried off.

I indicates a horizontal gauze st-rainer, which extends across the entire surface of the casing and catches and strains all juice falling from the straining-Wheel.

.T indicates a pipe or trough, through which the juice and bagasse particles are conveyed from the crushing-millto the strainer. This pipe J extends within the case to a point within the iian ges E, so as to readily discharge the juice and bagasse particles into the extended buckets D.

L indicates a spout or pipe, by which the strained juice is drawn from the bottom of the casing.

M indicates an inspection-glass in one end f of the casing, and N a door or man-hole in naled in a frame or casing and having a perforated periphery and radial iianges at the sides of said periphery, of the normally-extended buckets secured at their lower ends to said periphery and adapted to give When pressed and return to their normal position when pressure has been removed, as and for the purpose specified. j

2. In a cane-juice strainer, the combination, with the main frame or casing, of the straining-wheel suitably journaled therein having the perforated periphery and radial flanges at the sides thereof, the normally-extended perforated buckets secured at their lower ends' to said periphery and adapted to give when pressed and return to their normal position when pressure has been removed, and the horizontal bottom strainer arranged in the casing at a point between the base thereof and the bottom of the straining-Wheel, all adapted to operate substantially as specilied.

3. In a cane-j uioe strainer, the combination, with the main frame or casin g having feed and discharge channels suitably arranged therein, of the revolving straining wheel journaled therein having the perforated periphery, and the normally-extended buckets secured at their base to said periphery and adapted to give when pressed and return to their normal position when pressure has been removed, the pressure -roller journaled in bearings depending from the top of the casing in a suitable position to engage the friction-roller and face of the extended buckets, substantially as specified.

4. rl`he improved buckets described having the perforated face portion, the longitudinally-bent strips adapted to form a seat for the edges thereof `one side of each of said strips being extended longitudinally at the top and bottom thereof, to form bearings for the friction-roller and the transverse securing-rod, respectively, and the rearwardlyextended spring-arms, also secured in the longitudinally-bent strips, all adapted to be attached to and operate in conjunction with a perforated revolving straining-wheel and pressure-roller, substantially as specified.

In testimony whereof I afliX my signature in presence of two witnesses.
